History:
The majority of the inhabitants of Jaisalmer are Bhatti Rajputs, who take their name from an ancestor named Bhatti, renowned as a warrior when the tribe were located in the Punjab. Shortly after this the clan was driven southwards, and found a refuge in the Indian desert, which was henceforth its home. This area was part of Gurjar - Pratihara empire and until the 11th century was ruled by a powerful Bargujar King. Deoraj, a famous prince of the Bhati family, is esteemed the real founder of the Jaisalmer dynasty, and with him the title of rawal commenced. In 1156 Rawal Jaisal, the sixth in succession from Deoraj, founded the fort and city of Jaisalmer, and made it his capital as he moved from his former capital at Lodhruva (which is situated about 15 km to the north-west of Jaisalmer). In 1293, the Bhattis so enraged the emperor Ala-ud-din Khilji that his army captured and sacked the fort and city of Jaisalmer, so that for some time it was quite deserted. Some Bhatti's migrated to Talwandi, now Nankana Sahib in Distt. Nankana Sahib (Punjab, Pakistan) and others settled in Larkana (in Sind, Pakistan)under the name of Bhutto. In Nankana Sahib, the Bhatti Clan can be traced from the lineage of Rai Bhoe and Rai Bular Bhatti. After this there is nothing to record until the time of Rawal Sahal Singh, whose reign marks an epoch in Bhatti history in that he acknowledged the supremacy of the Mughal emperor Shah Jahan. The Jaisalmer princes had now arrived at the height of their power, but from this time till the accession of Rawal Mulraj in 1762 the fortunes of the state rapidly declined, and most of its outlying provinces were lost. In 1818 Mulraj entered into political relations with the British. Maharawal Salivahan, born in 1887, succeeded to the chiefship in 1891.
The Maharajas of Jaisalmer trace their lineage back to Jaitsimha, a ruler of the Bhatti Rajput clan. The major opponents of the Bhati Rajputs were the powerful Rathor clans of Jodhpur and Bikaner. They used to fight battles for the possession of forts, waterholes or cattle. Jaisalmer was positioned strategically and was a halting point along a traditional trade route traversed by the camel caravans of Indian and Asian merchants. The route linked India to Central Asia, Egypt, Persia, Africa and the West.

Geography:
Jaisalmer has an average elevation of 229 metres (751 ft). It is situated near the border of India and Pakistan in West Rajasthan, and covers an area of 5.1 km².

The average rainfall is 150 millimetres (5.9 in).
Jaisalmer is almost entirely a sandy waste, forming a part of the great Indian desert. The general aspect of the area is that of an interminable sea of sand hills, of all shapes and sizes, some rising to a height of 150 feet (46 m). Those in the west are covered with log bushes, those in the east with tufts of long grass. Water is scarce, and generally brackish; the average depth of the wells is said to be about 250 feet (76 m). There are no perennial streams, and only one small river, the Kakni, which, after flowing a distance of 28 metres (92 ft), spreads over a large surface of flat ground, and forms Lake Orjhil (The Bhuj-Jhil). The climate is dry and healthy. Throughout Jaisalmer only raincrops, such as bajra, jawar, motif, til, etc., are grown; spring crops of wheat, barley, etc., are very rare. Owing to the scant rainfall, irrigation is almost unknown.
